"Stunt, did people actually use supplements for bodybuilding prior to the ban of anabolics (in 89 or 91 or whenever it was)?"
CEPHISSIUS, anabolic steroids were added to Schedule III of the Controlled Substances Act in the Anabolic Steroids Control Act of 1990.
And YES, People (especially those involve within the weight lifting game) did use supplements prior to the ban of anabolics, but as BB said, it was limited and nothing like it is today.
I should add that the history of powered supplements is another very interesting story within this world of lifting heavy things and looking in the mirror.
I'll do my best to elaborate later but it all started when the Weider brothers and the Bob Hoffman crew (they were major competitors whom I personally witnessed on a couple of occasions) learned that once a customer bought a metal barbell and a shit-load of heavy plates, they seldom placed a second order because heavy stuff like barbells and plates simply don't wear out nor fall apart.
But if you offer a consumable, they would come back a second, third and fourth time.
And that it how it all started ..... but there is much more to that story which you may find to be of interest.
For instance ... the fact that neither Ben nor Bob was the first to offer powered protein in a 'cardboard' container.
More on all that stuff to follow if there is any interest.
SYNC.... I don't recall anything about Rose Hips back in them good old days except for their high vitamin C content.
